550cc injectors STI PINKS from 05 STI Clean and taken care of

[jspec240]

STI pinks 200$ shipped in the US Firm they are in excellent condition, Just removed and are individually wrapped and ready to ship. Also have a top feed fuel rail for 50$ brushed aluminum. Pics of that tonight.

I also have the rubber gromets that fit into the intake plenum as well as the top rubber O rings that go with it, not pictured.
They have been examined and have no wear or cracks. I added a little bit of light weight oil to preserve them also.

Hmm I though sti injectors were sidefeed?

[jspec240]

No sir.not JDM the pinks. The yellow 520cc USDM STI and I believe some newer year sti/legacy/ or baja have pinks that are side feed but the JDM pink top feed denso 9310's are the 565cc ones are side though^^^... Price drop 225 SHIPPED!!!! FIRM

STI injectors come in both top feed and side feed, depending on the year. The 07+ are top feeds and I am told that they need a 7/16 spacer to make them fit just right. I just bought a set for my SR20DET with an HKS fuel rail, so we'll see how the installation goes.

HMM Im doing my research so Im hoping there are more cc's :) get back soon

[jspec240]

OK Here are the specs I got from a wrx forum so If you have any concrete evidence that these are not what this explains. Please post whats different and the website it came from



A SET OF (4) 565CC STI PINK FUEL INJECTORS
PART NUMBER: TH510F
DIRECT STOCK REPLACEMENT
FITS ALL TURBOCHARGED SUBARU WRX 2002 - 2006+
The STI 565cc "pink" injectors are OE Subaru high-performance injectors found on the high horsepower STI, STI-RA, and S202 Impreza models. These injectors are factory rated at 525cc but because of the common "under-rating" system of Japanese manufacturers, these injectors have been independently tested to flow 565cc. We recommend the use of these injectors for applications of 240whp-300whp. A very good compliment for all IHI VF-series turbos.
Also compatible with KA24DE / E engines for turbo set ups as well as SR20DET upgraded turbos with the addition of a top feed fuel rail.

Yes please do let us know how it works out for you. It would be valuable input.

Thanks

OK Heres a REAL post that has been researched and was written by a knowledgeable NASIOC moderator. Mine are the JDM PINKS which are 550cc but have been flow tested to 565cc (separate reference )and are top feed. Here is the info on ALL of the subaru WRX/STI injectors with REAL data not just a simple post.

supporting mine are JDM STI 550cc top feed

Reference 2 - The JDM pinks when flow tested read "up to"565cc

Injector FAQ

What are the best fuel injectors? Fuel injectors should be purchased based on the best possible match between the flow rating and needs of your aftermarket turbo. This should be a determination by your tuner to provide the best possible match. It is better to opt on the side of too large if there is any possibility of maxing out the injectors with your upgrade plans. Bigger is not always better with injectors so it is always best to purchase injectors best suited for your application and upgrade as need as opposed to starting off too large. This online calculator (http://www.rceng.com/technical.htm#WORKSHEET) may assist you in the decision process. This post (http://forums.nasioc.com/forums/showthread.php?t=774458) by hotrod will also help. As well, ask your tuner for his recommendation on brands. It will be cheaper to buy the brand he is familiar with rather than wasting dyno time + tuner fees while he fiddles around with your rogue brand injectors.

What type of injectors do I need? Aside from matching the injector flow for your turbo/tuning needs, you need to get the correct type for your vehicle (http://forums.nasioc.com/forums/showthread.php?t=1218460#):

WRX uses high impedance top feed injectors
04-06 STI uses high impedance side feed injectors (also called bottom feed)
07+ STI uses high impedance top feed injectors

What is the difference between low and high impedance? Low impedance injectors need to be electrically adapted to work properly, and usually come with the required electronic components for this.




Is there a list of top feed injector sizes for the 2002-2008 WRX and 2007-2008 STI?

OEM 2002-2005 WRX 420 cc
Power Enterprise 510 cc
JDM STi "pinks" 550 cc

Is there a list of side feed injector sizes for the 2004-2006 STI?

OEM 2004-2006 STi 535 cc
DeatschWerks 650 cc
DeatschWerks 740 cc

*Ultimate Racing STI injectors are top feed injectors with a rail conversion kit to allow them to work as side feeds. They are also low impedance and come with a resistor pack kit to allow them to work as high impedance.

Who manufactures injectors?

Agency Power (http://www.agency-power.com/)
DeatschWerks (http://www.deatschwerks.com/)
Helix (http://www.helix-power.com/)
Perrin Performance (http://www.perrinperformance.com/)
Power Enterprise (http://www.power-enterprise.co.jp/) (low and high impedance versions)
RC Engineering (http://www.rceng.com/) (low and high impedance versions)
SARD (http://www.sard.co.jp/)
Ultimate Racing (http://www.ultimate-racing.com/) (low and high impedance versions)

Can I modify stock 02-05 WRX injectors for increased flow? Yes, though this route requires additional research, thought, time, and care than purchasing larger injectors.

600 cc injectors (http://forums.nasioc.com/forums/showthread.php?s=&threadid=495810)
740 cc injectors (http://forums.nasioc.com/forums/showthread.php?s=&threadid=478921) (Though this is the thread title and commonly known name, these modified injectors actually flow 850 cc when tested at the normal static fuel pressure of 43psi)

Can I modify stock 06+ WRX injectors or STi pinks for increased flow? Yes, but that would be a dumb move. These babies go for like $300 used. Sell them, buy 02-05 WRX injectors for like $150 and have them modded.

How do I install fuel injectors? Refer to the fuel injector manufacturer's instructions. For fuel injectors without instructions, below is a link to one of the better known fuel injector installation instructions:

I HOPE THIS FIXES ALL PROBLEMS CONCERNING WHAT PINKS ARE>>>>

[Seraphim38]

Excellent post. There now should be no debate about what the pink STI injectors are.

My only concern is that data is from a Subaru site and doesn't highlight any notes about their usage on an SR20DET.

Guys can figure out that the STI top feeds are far cheaper than your average SR20DET side feed injectors. If someone posts a definitive, comprehensive note on their installation experience it could spur on a migration towards more use of them in this community.

I have already ordered them with a top feed fuel rail for my SR20DET, but will be installing modified STI 800cc top feeds and will be hiring a mechanic to do the installation, but will post my personal experience about them when done.

[jspec240]

I will try to find a link but from what I have seen and been told. ALL wrx/STI have the same Low ohm's as the SR and KA so its a matter of what cc you are getting from what year and weather or not you need to convert to top feed.

For certian though the Pinks Will work on the SR20det and the KA24DE / E because if you can swap the SR to the KA then same goes for the STI injectors.

[jspec240]

All of the info needed is here.... Price drop to 200 Shipped... LAST call not will throw em on my SR if not.

[jspec240]

The last straw!!!! 200 shipped!!!!!!!
